Petratos’s goal in the Jets 5-1 thrashing of the Mariners came courtesy of a sublime piece of skill.

After receiving the ball just inside the box, the 24-year-old turned his defender to give himself space and unleashed a powerfully driven shot across the keeper that almost went through the top of the net.

It’s the type of goal Petratos is renowned for and the former Australian youth international said there’s no question he can repeat the feat.

 “Yes, why not?” he said.

 “I’ve just go to get myself in the box and get on the end of balls and I don’t see why I can’t score a few goals.

“I haven’t really set goals on how many I will score this season to be honest. I like to go out and have fun and I want to take a more relaxed approach this season. I’ve just got to work hard and combine with the players around me.

“But of course every game I go into I want to win. I’m going to give it my best to do what I can for the team and play to the best of my ability.”

Petratos is back in the A-League after his mid-season move from Brisbane Roar to K-League side Ulsan lasted just nine matches.

Along with the winger, the Jets have made a number of major signings including Roy O’Donovan, Venezuelan International Ronald Vargas and former Western Sydney Wanderers captain Nikolai Topor-Stanley.

Newcastle’s thrashing of the Mariners saw the new recruits have an instant impact with Vargas, Petratos and O’Donovan making key contributions.

After finishing on the bottom of the A League table last term, the skilful attacker feels the Jets squad can challenge for end of season honours in 2017-18.

“I don’t see why we can’t,” Pertatos said. “With the way the team is set up of course we want to finish on the top of the table.

“We have all spoken together about this, we’ve just got to believe and say it out loud and back ourselves and go for it.”

Petratos added, “Ronnie (Vargas) is a very smart player. You can see what Roy does and along with Andrew Nabbout they work hard and they are both goal scorers.

“We’ve just got to keep working hard and try and get the combinations going in the front third.”

And ahead of Newcastle’s first home game of the season against Perth Glory on Sunday, Petratos assured Jets fans that Ernie Merrick’s men would give everything for the win.

“We are going to go out and give it our best and try and entertain and be positive and show that we have a hard work ethic,” he said.

“It doesn’t have to be 5-0 it doesn’t have to be 5-1 it can be 1-0. The final score always varies and we are going to go and try and win the game.

“I feel very confident about the season ahead, we have a great squad and all the players all believe in themselves and I feel that we’ll do really well.”
